Question

A molecule contains
10% iron by mass.
mass of the
molecule is 67200,
The number of iron
atoms present in 0.5
mol of the molecule
(Atomic mass of Fe =
56 u)
120N
60N
C240N
56N​

Answer 1

Answer:

120N

Explanation:

mass =10

100grams of molecules cantains 10grams of iron

=67200×10/100

=6720

iron atomic weight=56

number of molecules= 6720/56

number of molecules=120N
